Power outage hits Fenno-Skan 2 link between Finland and Sweden
Mar 10th 2026
Fingrid says a substation malfunction caused an early Tuesday outage on the 800 MW Fenno-Skan 2 link; equipment was inspected and service restored with commercial operation set to resume around midday amid wider Baltic Sea security concerns.
- Fingrid reported an unexpected outage on the 800 MW Fenno-Skan 2 submarine cable early Tuesday.
- A Fingrid spokesperson said the outage appeared to be caused by a malfunction at a substation and that the undersea cable was not damaged.
- Fingrid inspected the affected equipment and restored the connection, with commercial operation due to resume around midday.
- The Baltic Sea region has been on high alert after multiple power and telecoms cable disruptions since Russia's 2022 invasion of Ukraine, prompting sabotage investigations.
- Authorities have flagged risks from a largely unregistered shadow fleet of ships and last month Finnish police arrested two people on a cargo ship suspected of damaging a Helsinki Tallinn cable.
